NAME

Raku port of Perl's sleep() built-in

SYNOPSIS

use P5sleep; # exports sleep()

DESCRIPTION

This module tries to mimic the behaviour of Perl's sleep built-in as closely as possible in the Raku Programming Language.

ORIGINAL PERL DOCUMENTATION

sleep EXPR
sleep   Causes the script to sleep for (integer) EXPR seconds, or forever
        if no argument is given. Returns the integer number of seconds
        actually slept.

        May be interrupted if the process receives a signal such as
        "SIGALRM".

            eval {
                local $SIG{ALARM} = sub { die "Alarm!\n" };
                sleep;
            };
            die $@ unless $@ eq "Alarm!\n";

        You probably cannot mix "alarm" and "sleep" calls, because "sleep"
        is often implemented using "alarm".

        On some older systems, it may sleep up to a full second less than
        what you requested, depending on how it counts seconds. Most
        modern systems always sleep the full amount. They may appear to
        sleep longer than that, however, because your process might not be
        scheduled right away in a busy multitasking system.

        For delays of finer granularity than one second, the Time::HiRes
        module (from CPAN, and starting from Perl 5.8 part of the standard
        distribution) provides usleep(). You may also use Perl's
        four-argument version of select() leaving the first three
        arguments undefined, or you might be able to use the "syscall"
        interface to access setitimer(2) if your system supports it. See
        perlfaq8 for details.

        See also the POSIX module's "pause" function.
